Advisory
Source description from Wordfence Intelligence, credited to Daniel Ruf.
The Restricted Site Access plugin for WordPress is vulnerable to IP Spoofing in versions up to, and including, 7.3.1 due to prioritizing getting a visitor's IP from certain HTTP headers over PHP's REMOTE_ADDR. This makes it possible to bypass IP-based limitations in certain situations.
